江苏省海头高级中学英语译林牛津版选修6Unit3同步教案(语法)

___________________________________________________________
Step2 Learning
时间
从句
主句
与现在事实相反
If +主语+动词的过去式(be-were)…
主语+ would / could/ might+动词原形
与过去事实相反
If+主语+had +过去分词
主语+ would/ could/might + have+过去分词
与将来事实相反
If+主语+were to/(should) + 动词原形
主语+ would / could/ might+动词原形
注: 当从句的if省略时, 句子要倒装, 如
If I were you, I would not do that.
___________________, I would not do that.
在if I /he/she/it 之后, 可用were代替was。两者在意义上没有区别, 但是were更为正式, 特别是在称述心存怀疑的事情时:
If she were ready, we would go.
在与将来事实相反的条件从句中,我们可以用were to或should +do来表示,如:
If I were to fail my English test, I would have to take it again at the end of the term.
If he should come tomorrow, I would talk to him about it.
虚拟条件句中的省略与倒装在非真实条件句中,如果有were, had, should, 我们可以将if省略,把这些词置于句首,采用倒装形式,如:
? If I should meet her, I would tell her.
= ______________________, I would tell her.
? If I were in your position, I would do it better.
= ______________________, I would do it better.
? If they had made preparations, they would have succeeded.
=________________________, they would have succeeded.
Step3 Further learning
● 错综时间条件句
非真实条件句中, 主句谓语动词所表示的动作和条件从句中谓语动词所表示的动作并不同时发生, 这时动词的形式并不完全按照上述表格来进行, 而需要按照各自的时间来调整, 这样的句子就叫错综时间条件句。
e.g.
1) If you had followed the doctor’s advice, then you would be all right now.
2) If I hadn’t finished my composition by now, I would be working on it tomorrow.
3) If she had prepared well for her lessons yesterday, she wouldn’t have so many difficulties now.
● 含蓄条件句
有时一个假设的情况并不用条件从句表示,而用其它方式来表示,这样的句子叫含蓄条件句。
用with, without等介词短语或分词短语或者独立主格结构来代替条件从句。
We might have died without your help.
=We might have died if you hadn’t helped us.
Having known in time, we could have stopped it.
= If we had known in time, we could stopped it.
